4 Basic Information (General)

4.1 Proper use

The balance you purchased is intended to determine the weighing value of material

to be weighed. It is intended to be used as a non-automatic balance, i.e. the mate-rial to be weighed is manually and carefully placed in the centre of the weighing plate.As soon as a stable weighing value is reached the weighing value can be read.

4.2 Improper Use

Do not use balance for dynamic add-on weighing procedures, if small amounts ofgoods to be weighed are removed or added. The stability compensation installed inthe balance may result in displaying an incorrect measuring value! (Example: Slowlydraining fluids from a container on the balance.)Do not leave permanent load on the weighing plate. This may damage the measuring

system.Impacts and overloading exceeding the stated maximum load (max) of the balance,minus a possibly existing tare load, must be strictly avoided. Balance may be dam-age by this.Never operate balance in explosive environment. The serial version is not explosionprotected.The structure of the balance may not be modified. This may lead to incorrect weigh-ing results, safety-related faults and destruction of the balance.The balance may only be used according to the described conditions. Other areas ofuse must be released by KERN in writing.

4.3 Warranty

Warranty claims shall be voided in case

Our conditions in the operation manual are ignored

The appliance is used outside the described uses

The appliance is modified or opened

Mechanical damage or damage by media, liquids, natural wear and tear

The appliance is improperly set up or incorrectly electrically connected

The measuring system is overloaded

13/71

ABT-BA-e-0911 13

4.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the bal-ance and, if applicable, the testing weight, must be checked regularly. The responsi-ble user must define a suitable interval as well as type and scope of this test. Infor-mation is available on KERNs home page (www.kern-sohn.com with regard to themonitoring of balance test substances and the test weights required for this. InKERNs accredited DKD calibration laboratory test weights and balances may becalibrated (return to the national standard) fast and at moderate cost.

5 Basic Safety Precautions

5.1 Pay attention to the instructions in the Operation Manual

Carefully read this operation manual before setup and commissioning, even if youare already familiar with KERN balances.

5.2 Personnel training

The appliance may only be operated and maintained by trained personnel.

6 Transport and storage

6.1 Testing upon acceptance

When receiving the appliance, please check packaging immediately, and the appli-ance itself when unpacking for possible visible damage.

6.2 Packaging

Keep all parts of the original packaging in case you need to return the appliance.Only use original packaging for returning.Before sending, disconnect all connected cables and loose/movable parts.Attach possibly existing transport safeguards.

7 Unpacking, Setup and Commissioning

7.1 Installation Site, Location of Use

The balances are designed in a way that reliable weighing results are achieved in

common conditions of use.You will work accurately and fast, if you select the right location for your balance.

Therefore, observe the following for the installation site:

Place the balance on a firm, level surface;

Avoid extreme heat as well as temperature fluctuation caused by installingnext to a radiator or in the direct sunlight;

Protect the balance against direct draughts due to open windows and doors;

Avoid jarring during weighing;

Protect the balance against high humidity, vapours and dust;

Do not expose the device to extreme dampness for longer periods of time.Non-permitted condensation (condensation of air humidity on the appliance)may occur if a cold appliance is taken to a considerably warmer environment.In this case, acclimatize the disconnected appliance for ca. 2 hours at roomtemperature.

Avoid static charge of goods to be weighed or weighing container.

If electro-magnetic fields or static charge occur, or if the power supply is unstablemajor deviations on the display (incorrect weighing results) are possible. In that case,the location must be changed.

7.2 Unpacking

Carefully remove the balance from the packaging, remove plastic cover and setup

balance at the intended workstation.

7.5 Initial Commissioning

A warming up time of 4 hours after switching on stabilizes the measuring values.The accuracy of the balance depends on the local acceleration of gravity.Strictly observe hints in chapter Adjustment.

7.5.1 Turning On the Power

1. Supply power to balance via mainsadapter. After the balance performs aself check, calibration will be automati-cally executed. During this process, thedisplay will change as follows. CHE 5,CHE 4...... CHE 0, CHE 2, CHE 1, CAL 2 CAL 0 , CAL-End, oFF.This adjustment can be interrupted im-

mediately after switching-on the powersupply by actuating the [ON/OFF]-key.However, at least one adjustment mustbe carried out before the balance canbe used.

2. Actuate the [ON/OFF] key. After all dis-plays appear, the gram (g) symbol ap-pears.

3. Pressing the [ON/OFF] key again turnson the standby symbol and puts the

balance in standby (warm up) status.Current time (see ch. 13.5) will be dis-played.

19/71

ABT-BA-e-0911 19

8 Adjustment

As the acceleration value due to gravity is not the same at every location on earth,each balance must be coordinated - in compliance with the underlying physicalweighing principle - to the existing acceleration due to gravity at its place of location

(only if the balance has not already been adjusted to the location in the factory). Thisadjustment process must be carried out for the first commissioning, after eachchange of location as well as in case of fluctuating environment temperature. To re-ceive accurate measuring values it is also recommended to adjust the balance peri-odically in weighing operation.Observe stable environmental conditions. Stabilisation requires a warm-up period of1 or 4 hours (for models d = 0.01 mg). Ensure that there are no objects on theweighing plate.

8.1 Automatic adjustment via PSC

The default setting for balances of the series ABT ("PSC ON") prompts automaticadjustment via the PSC function.The moment a change in temperature is detected this function uses the internal tareweight to carry out fully-automatic adjustment with the help of a temperature sensor.If PSC is left ON, when there is a temperature change that would influence sensitiv-ity, span calibration executes automatically to maintain the sensitivity of the balance.Adjustment in weighing mode is carried out automatically under the following condi-tions:

(1) If a change in environmental temperature (0.5 C) occurs;

(2) When about four hours has passed since the previous calibration.

(3) When the balance is switched from standby status to weighing modeand condition (1) or (2) has been met.

(4) When balance was disconnected from the mains.

If one of the above conditions was met in weighing mode, the weight symbol flashesfor about two minutes in order to notify the pending adjustment; afterwards the dis-play will show "PSC run". During operation, the display will automatically change andthe motor sound of the weight loading system is heard. In order to ensure properPSC operation, prevent vibrations and air flow. As soon as the display in grams re-appears after completing adjustment via PSC, the balance returns to weighing mode.The sensitivity before and after adjustment is slightly different. Also, no measure-ments can be made during adjustment. To prevent a start-up of adjustment during ameasuring process you have to actuate the [ON/OFF] key as soon as the weightsymbol starts flashing. This will interrupt automatic adjustment.

8.2 Automatic adjustment via Clock-CAL

(only models ABT 100-5M, ABT 120-5DM, ABT 220-5DM)

With the help of its internal adjusting weight and integrated clock the balance can beset to carry out automatic adjustment at set times (up to three times daily). Clock-CAL is a very convenient function, when calibration reports are desired to be madefor regular calibrations, or when wishing span calibrations during break times to avoidinterruption of measurement work.The weight symbol blinks for about two minutes as notification of span calibrationbefore it begins. Automatic adjustment can be stopped by actuating the [ON/OFF]key during this message.

9 Verification

General introduction:According to EU directive 90/384/EEC balances must be verified if they are used asfollows (legally controlled area):

a) For commercial transactions if the price of goods is determined by weighing.b) For the production of medicines in pharmacies as well as for analyses in themedical and pharmaceutical laboratory.

c) For official purposes.d) For manufacturing final packages.

In cases of doubt, please contact your local trade in standard.

Verification instructions

An EU type approval exists for balances described in their technical data as verify-able. If a balance is used where obligation to verify exists as described above, itmust verified and re-verified in regular intervals.Re-verification of a balance is carried out according to the respective national regula-tions. The validity for verification of balances in Germany is e.g. 2 years.The legal regulation of the country where the balance is used must be observed!After verification the balance is sealed at the indicated positions.Verification of the balance is invalid without the "seal".

Position of the official seals:

Balances with obligation to verify must be taken out of operation if:

- The weighing result of the balance is outside the error limit. Therefore, inregular intervals load balance with known test weight (ca. 1/3 of the max.load) and compare with displayed value.

- The reverification deadline has been exceeded.

13.1.2 Anti-convection mode

If measurements have to be taken under unavoidable ambience conditions, (e. g.changing air condition systems) convection occurring within the weighing space mayresult in fluctuations in the display on the balance after the stability display has ap-peared. The small range (readability 0.01 mg) of series ABT is particularly suscepti-ble to this effect.Anti-convection mode adjusts the timing of appearance of the stability mark. Notethat the stability mark will then appear at a late timing.

Repeatedly press the [CAL] key until "ConvECt" appears.

To set anti-convection mode, press the [TARE] key.

Setting of this mode can be confirmed only in settings checkdisplay (see ch. 12.6).

13.1.3 High-stability Mode

The balances of series ABT are designed to react only minimally to the effects of vi-brations and drafts. However, if it must be set up in a location with poor conditions,

use this function to reduce the effects of vibration or air current even further. There isa slight increase in the reaction time of the balance but the display itself is stabilized.

Repeatedly press the [CAL] key until "ConvECt" appears.

To set high stability mode, press the [TARE] key.

14 Application Functions

14.1 Parts counting

With parts counting you can either count parts into a container or remove parts from

a container. To count a greater number of parts the average weight per part has tobe determined with a small quantity (reference quantity). The larger the referencequantity, the higher the counting exactness. High reference must be selected forsmall parts or parts with considerably different sizes.The process has four steps:

Tare the weighing container

Determine the reference unit

Weigh in the reference unit

Count the items

Condition: Function "U- PSC" activated (ch. 11.3)

(When PCS is used for thefirst time)

Repeatedly press the [UNIT] until display is in percentagemode. The display symbol PCS pops up.

If you are using a weighing container use the [TARE] key for

taring.

To determine the reference piece number, place 10, 20, 50 or100 counting parts on the balance.

Press the [CAL] key

Repeated pressing of the [CAL] key allows the change betweenthe following reference piece numbers "Ld 10", Ld 20,Ld 50and Ld 100.

Important: The larger the reference quantity, the more accuratethe parts counting.

(When loading 20 pieces)

When standstill control ( ) is complete, confirm your referencepiece number by pressing the [TARE] key.

The display shows "SEt" for several seconds and the stored ref-erence piece number is displayed.

Now you can fill the items to be counted into the container.The respective quantity is shown in the display.

Repeated pressing of the [UNIT] key changes the display value,

e. g.: [g] [%] [Pcs] [ct]

Note:Error message "Err 20" indicates that the weight for the reference piece number istoo low.

14.2 Percent determination

Percent weighing allows to display weight in percent, in relation to a referenceweight. The displayed weighing value is stored as a standard percent value(default setting: 100%).

Condition: Function "U- %" is activated (ch. 11.3)

(When PCS is used for thefirst time)

Repeatedly press the [UNIT] key until the display is in percent-age determination mode. The display symbol % pops up.

If you are using a weighing container use the [TARE] key fortaring.

Put on reference weight (=100%)(minimum weight: Readability d x 100)

When standstill control ( ) is complete, press the [CAL] key.The reference weight is saved.

Remove reference weight.

From now on the placed weight will be shown as %.

Repeated pressing of the [UNIT] key changes the display value,

14.4 Auto Print

Using Auto Print allows measurement results to be automatically output via the RS-232C interface without pressing the [PRINT] key individually with every measure-ment. An issue will be made after standstill control ( ) is complete. The next meas-urement is done after removing the items from the weighing plate and the display is

returning to a value within the 3-fold of the zero range.

Important: This mode can be applied to any unit.

The initial load of the balance must be kept within the 5-fold of the zerorange.

14.5 Add up mode

An optional number of single weighing processes are automatically added up to atotal sum, e.g. all single weighing processes of a batch or if you have to carry out agreat number of measurements of small samples.When the standstill control ( ) is complete the weighing value is automatically issuedto the optional printer. The displayed value is added into the total adding memory.Afterwards automatic taring will take place. This is repeated newly every subsequenttime a new sample is placed on the weighing pan. When the last single weighingprocess is finished, press the [ON/OFF] key to receive the total sum ("TOTAL=").

Important: This mode can be applied to any unit.

The initial load of the balance must be kept within the 5-fold of the zerorange.

Weight of sample 10 x zero range (zero range = 0.25 e)

If during the use of multiple range balances the smallest readability digitwas turned off by pressing the [1d/10d] key, evaluation is based on thelatest add-on value displayed before.
